Abstract

The present invention discloses a method and a device for adjusting a display picture to solve a problem in the prior art that when Greenish phenomenon of a liquid crystal display screen is alleviated, aperture ratio of the display panel is decreased so that power consumption of the screen is increased. The method for adjusting the display picture includes the steps of: receiving a first clock signal for controlling a data line voltage signal for a pixel of the first color in the display picture and receiving a second clock signal for controlling data line voltage signals for pixels of the other colors; and making a pulse width at high level of the first clock signal smaller than a high level pulse width of the second clock signal, wherein the first color is closer to green than other colors.

Description

FIELD OF THE INVENTION

[0001] The present invention relates to the field of display technology, and particularly to a method and a device for adjusting a display picture.BACKGROUND OF THE INVENTION

[0002] With the progressive development of the liquid crystal display technology and the price advantage of the liquid crystal display screen, the liquid crystal display screen is used as a display screen of various electronic apparatus in our lives or a decorative electronic display device, which has gradually become a trend of the liquid crystal display screen. The liquid crystal display screen in the prior art has been widely used in various kinds of electric appliances, e.g. a liquid crystal display television, a mobile telephone and so on.

[0003] When a specific display picture is displayed on the liquid crystal display screen, a greenish phenomenon (i.e., Greenish (green flickering) phenomenon) may occur. FIG. 1 illustrates a timing diagram of voltage signals applied to the data lines of ...
